These underwear are so great to work out in that I'm going to buy more and wear these all the time under looser clothing. I do not know what these are like under tight clothing. I purchased my first pair at the Road Runner store. I got a size medium because that's the size I wear in my other non-work out underwear. They look super small, but they stretch. I especially like these underwear because they are stylish and cute. You look like you are wearing cute shorts, not briefs. I'm pear shaped, 5'6" about 135lbs. I don't have a small bottom but these actually cover all of it. They do ride up a little in the front when I lift my leg or squat down, but don't let this stop you from buying these. The leg opening is not tight and if you're wearing roomy work out pants, you won't be able to see it. The leg opening does stay in place in back though. I've been searching a while for a boyshort that held me in without giving me a muffin top or showing lines on my thighs and these fit the bill. The back vertical seam in my roomier work out pants used to actually stick in between my cheeks but these boyshorts prevent that.

I have been wearing Under Armour boyshorts for running and training and decided to give these a shot. The RRS brand is far superior - totally comfortable and wicks sweat away. These are perfect and completely non-irritating. I could not be happier with them and purchased them in all colors.

I am training for a 40 mile walk and wanted something comfortable and moisture wicking that would not "ride-up" at any time. I love these, but did not take the warnings of other buyers when they shared that this product runs smaller than usual. I wear a size 6 and the small was too small. The mediums fit perfect.

I always wear boy shorts under my running tights, and I've tried many brands over the years. I wasn't sure how these were going to work, but they are truly amazing! The fit, fabric, and sizing are all perfect, and they are far more comfortable to run in than any other brand I've tried. I could not be happier with this purchase!

I purchased this item specifically for cycling. I have been looking for years for underwear for cycling that does not irritate or ride up . It is absolutely perfect. No uncomfortable elastic or seams. Stays in place.

I use these every day. I have a terrible back side with a flat butt and cellulite but I am s smaller frame. These not only are comfortable but they give my butt a lift and a better shape. I love them and would totally recommend.

I don't usually write reviews, but these are amazing.Also, to all of you wearing underwear under running shorts, stop doing that! Don't wear underwear when you work out! It causes chafing and it's unnecessary. All decent workout clothing is created without seams in bad places, so you don't need underwear to protect you from your workout clothes. HOWEVER, do buy these boy shorts for everyday use. They are really soft and they wash well and they look incredible. My boyfriend is buying me more because he loves how they look on me.

I bought these as I started uping my running mileage. They are very soft ,but the boy cut is not the answer for me. The bottom of the shorts roll up. I bought large (following the comments on this style) I'm a size 8. Maybe I just bought the wrong size. However the front of the short seems to fit ok, but the back feels a bit short. I do like the material, so I just won't buy this style again.

I bought three of these in pink. They fit well for jogging, but during gym workouts they roll and bunch up during squats and jump-ups. After two months the hem around the legs came out in the wash. Now they roll immediately.

I bought these boy shorts to be a seamless fit under my dress pants. They are soft, stretchy.The fit is frustrating. It does not fit over my rearend very well. I am not overly large. Once the shorts are up and over my cheeks, the "shorts" part are now more like standard panties, but the front "short" part is lower. It does not take long for the extended leg to roll and create a "bulk" spot at the crease of my legs.I would like to see the legs of the shorts to be longer and a little more room in the seat.

I have been searching for a good panty to wear while working out / running for about a year now. None of them have worked out and all are either uncomfortable or irritating. These boy shorts are perfect and the material is very comfortable. They fit great, do not ride up, and actually stay in place while running and working out. These are way better than anything from Under Armour or Moving Comfort (two of the other highly rated workout underwear that did not work for me). I highly recommend these and you won't be disappointed.

I ordered these for dirt biking. Nothing worse than your butt cheeks being sawed in half by improper under garments! The legs did ride up so I'll keep looking for this style that has better leg grips. Three stars because they were comfy and the style was perfect. Lost two stars because the legs rolled and they seemed to stretch a size to large by the end of our ride.

These boyshorts are great; they stay in place, true to size and very comfortable. No irritating seams. I practically live in workout clothes and have tried many different brands....these are by far my favorite and will buy more.

I liked the soft feel of the fabric. I did not like how the legs bunched up when I put on my work out pants. I am walking the 3 day 60 miles in 3 days. I have to have something that is comfortable. I am diabetic with an insulin pump and need to keep the infusion set dry. The style is a personal prefernce. I prefered a different style. It would of been nice to buy all in the store. The stock was very limited had to order more online, as they did not come in their shipment.

I use this for running and Krav Maga workouts. I like the material and the size, but it always curls up at my upper thigh...a little annoying, but okay. The item says tagless but Roadrunner actually does have a tag on it. I asked and the girl at the counter stated that was the first time anyone had ever mentioned it being tagless but not.

Everyone else seemed to really love these boyshorts, so I decided to give them a try, particularly because I wanted a pair of shorts that would fit under my yoga/hot yoga shorts that wouldn't show an underwear line, and I wasn't sure how I felt about "athletic" thongs. The first day that I tried these on, just to wear around town, they were not comfortable and seemed to chafe in ... uncomfortable areas :-/ I have to say that it was the first time something like that has happened to me.... After a few wearings it has gotten better though, to the point that it's now fine to wear.

My main gripe is that the fabric all around the leg holes roll up pretty badly, so although I don't have the typical panty line showing through, I get these weird bulges right below my behind where the fabric has rolled up. I'm not sure if that's just a thing with boyshorts in general. Maybe I just chose the wrong style to wear for yoga! For running I guess these pants would be just fine.

I am a runner and a rock climber, and occassionally hit the gym. I've been looking for undergarmets that are comfy and do what they are suppose to. So far I've only worn mine once while climbing. They were a little warm for climbing on a hot day, but they dried quickly and are super soft. To add to all that they stayed in place, which is saying something for climbing. Even after only one wear I am ready to buy more. Great find!
